DST is reducing the demand for 4% to 5% on average
Next Sunday (18) at 0h, millions of Brazilians have to advance clocks by one hour. It is the beginning of the season 2015/2016 of summer time in the states of Rio Grande do Sul, in Santa Catarina, Paraná, São Paulo, in Rio de Janeiro, Espirito Santo, Minas Gerais, Goias, Mato Grosso, Mato Grosso South and Federal District.
The main objective of the measure is, according to the National Electric System Operator (ONS), the reduction in demand in the peak period, between 18h and 21h. The strategy is to leverage the intensification of natural light throughout the day during the summer to reduce energy expenditure. Between the months of October and February, the days are longer in some regions because of the Earth's position relative to the Sun, and natural luminosity can be better utilized.
According to the Ministry of Mines and Energy (MME), DST is a reduction in demand on average 4% to 5% and saves the country to suffer the overload consequences on the network during the hottest season of the year where the use of electricity for refrigeration, air conditioning and ventilation peaks.
According to the MME, when demand decreases, companies that operate the system can provide better service to the consumer, because the transmission lines are less burdened. For hydropower, the water stored in the reservoirs can be important for a future drought. For consumers in general, the fuel or coal that did not need to be used in thermoelectric avoids tariff adjustments.
According to the ONS, in the summer time 2014/2015, reducing demand at peak hours was about 2,035 megawatts (MW) in South East / Midwest, equivalent to twice the consumption of Brasilia around the time he was into force. In South Subsystem, the reduction was 645 MW, corresponding to a saving of 4.5%.
The gains achieved by the reduction of global energy consumption, which takes into account all hours of the day, there were about 200 MW in Subsystem Southeast / Midwest, which is equivalent to the monthly consumption of the city of Brasilia, and 65 MW average in Subsystem Sul, Florianópolis equivalent to the monthly consumption.
According to the ONS press office, the estimated savings for the 2015/2016 summer schedule will be announced in the coming days and should not be too different from last year.
Currently, the Brazilian daylight saving time is regulated by Decree 8112 of September 30, 2013, which revised the Decree No. 8556 of 8 September 2008. It always starts on the third Sunday of October and ends on the third Sunday February of the following year, except when it coincides with the carnival, in which case it is postponed to the following Sunday.
